Abstract
The present invention relates to a wiper apparatus in which it is easy to replace a wiper blade without this leading to any erroneous operation. When a wiper operation has been stopped by a wiper driving apparatus 31, the wiper driving apparatus causes the wiper arms to first move to a housing position and then stops the wiper arms. When wiper blades are to be replaced, an IG switch 33 is turned off during a wiper operation. If the IG switch 33 is turned off while the wiper arms are within a first stopping range, then the wiper arms are stopped at that position and the blades are replaced. If the wiper arms are stopped outside the first stopping range, then they are first moved to a bottom inverted position or a housing position and are then stopped.
